Last year I purchased two 27" Series 395 Channel Balance, option: 2640. On the Viking windows I was repairing, the 2640 option was clearly marked. The new parts were excellent and the repair went extremely well.

I have another Viking window that needs repair. It has 21" channel balance, but the marking is 2090. (2090 BF BSI 28, see attached photo).

The 21" Series 395 Channel Balance on your site does not list a 2090 option.

Please advise.

2090 is part of an outdated weight system. To choose the correct spring strength option, you'll need to weigh the window sash and follow the chart under the product description to choose the correct option. Thank you!

OK, I weighted the sash and it is 26.2 lbs.

Does that mean I order option 2050 for 23-27 lbs, or

option 2030 for half the weight, because there are two balances?

Yep, you'll need a 2050 option since both balances need to be able to support your 26-pound sash.
